Farmed Yellowtail Production
Oita Prefecture — Japan's Second-Largest Producer


Located in southern Oita Prefecture, Kamae
is blessed with lush mountains and the pristine waters of the Bungo Channel,
making it an ideal fishing town for aquaculture.

and ranks among the country's leading producers of farmed yellowtail.

Declining Fish Catches and Fewer Fishermen
Along with an Aging Workforce

In 2019, Japan's fisheries and aquaculture production fell to
4.16 million tons, the lowest level since records began in 1956.
Both fish populations and the number of fishermen continue to decline.
Over the past 30 years, the number of fishermen has declined by 61%, leaving only about 150,000 today.
The average age of fishermen is 56.9 years, with 40% aged 65 or older.

Our goal is to build one of
Japan's leading seafood brands
and help secure the future of sustainable aquaculture.

The average age of the Namii Maruten Suisan team is just 30 years.

From Kamae, Saiki City, Oita Prefecture, we are driving the future of Japan's fisheries by embracing digital transformation (DX) and creating a workplace where young people can thrive.
We strive to raise fish that even younger generations will want to eat.
Through aquaculture technologies that go beyond what nature alone can achieve, we believe the future of seafood is evolving.
